Unlock Unlimited n8n Workflows for Claude with MCP Tools

Experience the power of seamless automation by exposing unlimited n8n workflows as Claude tools without ever hitting MCP tool limits. With the tag "mcp", your workflows are instantly discoverable and ready for action.

What this workflow does

• The workflow begins by receiving a request through the MCP Server Trigger set to the path `claude`. Alternatively, it can be initiated as a sub-workflow with input parameters including `tool`, `Id`, and up to five optional fields.
• Requests are then routed based on the `tool` input value: either to list tools through the `search tool` or to execute a specific tool using `execute tool`.
• For the `search tool`, it taps into the n8n API to fetch workflows that are tagged with `mcp`. This function retrieves essential details such as name, description, and id of each workflow, compiling them into a single, coherent response containing a `Tools` list.
• In the case of `execute tool`, it runs the requested workflow by referencing the provided workflow `Id`. Once initiated as a sub-workflow, it waits for execution to complete and then aggregates the output into a unified response returned to the caller.

Use cases

• Perfect for n8n users who need to expand their automation capabilities by leveraging Claude as an interface without being constrained by MCP tool limits.
• Ideal for automation engineers designing intricate workflow systems that require seamless integration and management.
• A valuable resource for SaaS operators looking to streamline their operational processes through dynamic workflow exposure.

Technical details

• Nodes/Tools Utilized: n8n, Set, Switch, Aggregate, Sticky Note, Execute Workflow
• Requirement: An n8n API credential capable of listing and reading workflow details
• Setup: Workflows must be tagged with `mcp` and described clearly for client accessibility. Ensure MCP endpoint details are configured for your MCP client under the `claude` path.
